You let out a howl towards the sky that bolsters and inspires your allies. As a bonus action you and creatures you choose within 30ft and that can hear you receive temporary hitpoints equal to your half your proficiency bonus (rounded down) + 1 extra temporary hitpoint per creature affected, to a maximum of 5 extra temporary hitpoints.

You carry the unique traits of your canine progenitors within you. Choose one of the following Ancestries:

Guardian. 

Vigilant. You cannot be surprised while you are conscious.

Watchdog. You have advantage on any checks made to keep watch over someone or something, and you can finish a long rest with only four hours of uninterrupted rest as opposed to 8 hours.

Hound.

Adept Tracker. You gain proficiency in the Survival skill, in addition you have advantage on any Survival checks made to track down any objects or creatures.

Hounds Intuition. Once you reach 2nd level, you always have the Locate Object spell prepared, and once you reach 7th level you always have the Locate Creature spell prepared. Neither of these spells count against your total number of spells known. Once you cast either spell with this trait you can't cast that spell with it again until you finish a long rest. You can also cast either of those spells using any spell slots you have of the appropriate level.

Shepherd.

Commanding Presence. You have proficiency in the Intimidation skill.

Shepherd's Command. You bark an intimidating or inspiring command to reposition others. On your turn when you take the attack action you can replace one of your attacks with a commanding bark, creatures within a 15ft cone in front of you that can hear you are affected in one of two ways, you choose each time you use this trait:

• Herd. Creatures you select can spend their reaction to move up to their speed. This movement does not provoke opportunity attacks.
• Repel. Creatures you select must make a Wisdom saving throw against a DC equal to 8 + your proficiency bonus + your Constitution modifier or be frightened of you until the start of your next turn, and must immediately use their reaction (if available) to move up to their movement speed away from you. This movement provokes opportunity attacks.
